Interface VirtualMachines

All Superinterfaces:

AdminAware, Iterable<VirtualMachine>, StatisticsMonitor

public interface VirtualMachines
extends AdminAware, Iterable<VirtualMachine>, StatisticsMonitor

Virtual Machines hold all the different VirtualMachines that are currently discovered.

Provides simple means to get all the current virtual machines, as well as as registering for virtual machine lifecycle (added and removed) events.

Provides the ability to start a statistics monitor on all current virtual machines using StatisticsMonitor.startStatisticsMonitor(). Newly discovered virtual machines will automatically use the statistics monitor as well.

Method Detail

getVirtualMachines

VirtualMachine[] getVirtualMachines()

Returns the currently discovered virtual machines.

getDetails

VirtualMachinesDetails getDetails()

Returns the aggregated details of all virtual machines.

getStatistics

VirtualMachinesStatistics getStatistics()

Returns the aggregated statistics of all virtual machines.

getVirtualMachineByUID

VirtualMachine getVirtualMachineByUID(String uid)

Return a virtual machine by its uid.

getUids

Map<String,VirtualMachine> getUids()

Returns a map of virtual machines with the key as the uid.

getSize

int getSize()

Returns the number of virtual machines current discovered.

isEmpty

boolean isEmpty()

Returns true if there are no virtual machines, false otherwise.

getVirtualMachineAdded

VirtualMachineAddedEventManager getVirtualMachineAdded()

Returns the virtual machine added event manager allowing to add and remove VirtualMachineAddedEventListeners.

getVirtualMachineRemoved

VirtualMachineRemovedEventManager getVirtualMachineRemoved()

Returns the virtual machine removed event manager allowing to add and remove VirtualMachineRemovedEventListeners.

addLifecycleListener

void addLifecycleListener(VirtualMachineLifecycleEventListener eventListener)

Allows to add a VirtualMachineLifecycleEventListener.
